The pair created a great commotion as they whirred past scattered houses and emerged into the keen, cold air of the marshland. A few cars met en route actually slowed up, and heads were thrust out to peer in wonder. Women in them were scared, and enjoined drivers to be careful, while men explained laughingly that a couple of joy-riders were being chased by a motor "cop." It was neck or nothing now for Voles, and when these alternatives offered, he never hesitated as to which should be chosen. He knew he was in desperate case. The pace; the extraordinary appearance of a hatless man and a girl with her hair streaming wild--for Winifred's abundant tresses had soon shed all restraint of pins and twists before the tearing wind of their transit--would create a tumult in Hoboken. Something must be done. He must stop the car and shoot that pestiferous cyclist, who had sprung out of the ground as though one of Medusa's teeth had lain buried there throughout the ages, and become a panoplied warrior at a woman's cry. He looked ahead. There was no car in sight. He peered over his shoulder. There was no cyclist! Petch had not counted on this frenzied race, and his petrol-tank was empty. He had pulled up disconsolately half a mile away, and was now borrowing a gallon of gas from an Orange-bound car, explaining excitedly that he was "after" a murderer! Voles laughed. The fiend's luck, which seldom fails the fiend's votaries, had come to his aid in a highly critical moment. There remained Winifred. She, too, must be dealt with. Now, all who have experienced the effect of an anesthetic will understand that after the merely stupefying power of the gas has waned there follows a long period of semi-hysteria, when actual existence is dreamlike, and impressions of events are evanescent. Winifred, therefore, hardly appreciated what was taking place until the car stopped abruptly, and the stupor of cold passed almost simultaneously with the stupor of anesthesia. But Voles had his larger plan now. With coolness and daring he might achieve it. All depended on the discretion of those left behind in Gateway House. It was impossible to keep Winifred always in durance, or to prevent her everlastingly from obtaining help. That fool of a cyclist, for instance, had he contented himself with riding quietly behind until he reached the ferry, would have wrecked the exploit beyond repair. There remained one last move, but it was a perfect one in most ways. Would Fowle keep his mouth shut? Voles cursed Fowle in his thought. Were it not for Fowle there would have been no difficulty. Carshaw would never have met Winifred, and the girl would have been as wax in the hands of Rachel Craik. He caught hold of Winifred's arm. "If you scream I'll choke you!" he said fiercely.
